Metabolite Identification
Common NamePC(18:0/P-18:0)
DescriptionPC(18:0/P-18:0) is a phosphatidylchloline (PC). It is a glycerophospholipid in which a phosphorylcholine moiety occupies a glycerol substitution site. As is the case with diacylglycerols, phosphatidylcholines can have many different combinations of fatty acids of varying lengths and saturation attached to the C-1 and C-2 positions. PC(18:0/P-18:0), in particular, consists of one octadecanoyl chain to the C-1 atom, and one 1Z-octadecenyl to the C-2 atom. In E. coli, PCs can be found in the integral component of the cell outer membrane. They are hydrolyzed by Phospholipases to a 2-acylglycerophosphocholine and a carboxylate.

Chemical Taxonomy
Description belongs to the class of organic compounds known as 1-acyl,2-(1z-alkenyl)-glycerophosphocholines. These are glycerophosphocholines that carry exactly one acyl chain attached to the glycerol moiety through an ester linkage at the O1-position, and one 1Z-alkenyl chain attached through an ether linkage at the O2-position.
